摘要
对聊城大学几种木本植物的形态特征、物候期、生长规律、开花习性进行了研究,结果表明:温度和光照是影响开花物候的两大主要因素,不同木本植物的开花时间不同,同一种类单株开花时间因树龄和树势而异,短时间的温度异常对开花物候影响不显著。在所观测的不同木本植物间最早与最晚发芽日期可差10 d,最早与最晚盛花日期可差50 d,其中桃树的始芽期和始花期最早,石榴树的最晚。
The morphological characteristics,phenophase,growth laws and flowering habits of several kinds of woody plants in Liaocheng University were studied. The results showed that the temperature and the sunshine duration were the important influencing factors of the flowering phenophase. The flowering time of different woody plants were different. And the flowering time of individual plant in the same kind was different with the tree age and tree vigor. The flowering phenophases of these kinds of plants weren＇ t obviously influenced during short-time temperature anomalies. While the woody plant of early germination budded about 10 days earlier than that of latest germination,the kind plant of early flowering blos- somed about 50 days earlier than that of latest flowering. Among those, the initial bud period and initial flowering period of peach were the earliest and that of pomegranate tree was the last.
